DRILLING MACHINE? Application filed November 23, 1925.;Seria1 No... 70,902.

This inventioncontemplates the provision of a drilling machine capable of being moved from place to place with a minimum of effort, and adapted to be operated from the 5 traction wheels of a motor operated vehicle, subsequent to jacking the wheels 05 the ground, the drilling mechanism aswell as the controlling elements of the vehicle being operated by a plurality of levers conveniently located at one end ofthe machine.

Thenature and advantages of the. invention will be better understood when the following detailed description is read inconnection with the accompanying drawings, the invention'residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a side "elevation of the machine. Figure-2 is a top plan view. Figure 3 is a fragmentary end elevation. Figure l is a fragmentary longitudinal sectional View.

Figure 6 is a detail view of the sand reel. 30 Figure 7 is an enlarged transverse sectional view showing the manner in which the arched shaped member is mounted for operating the drop beam.

Figure 8 is a detail view showing the manually operable means for rotating the drill reel. a

Referrin to the drawings in detail, 10 represents the frame of a motor operated truck or vehicle upon which is supported an auxiliary frame like structure indicated generally at 11, the latter supporting the drilling mechanism to be hereinafter described. It might here be stated that this mechanism is operated by the motive power of the vehicle. by jacking the traction wheels off the ground, one of which wheels is indicated at 12,.and associated with. each wheel is a gear 13. Thesegears are riveted on the brake drums of the respective wheels.

The drilling mechanism. includes a sand reel 14;" which is loosely mounted upon a shaft 15', the latter being journalled in suitable bearings on the auxiliary frame v11. This shaft 15 supports at the ends thereof sprocket wheels 16, over each of'which and as the adjacent gear or sprocket wheel l3 is trained an endless chain 17. After the wheels 12. of the vehiclehave been acked 05 of the ground, they. are supported in this position by means of blocks orother suitable means 18 upon which the frame 10 is adapted to rest. Manifestly, theshaft 15 is rotated from the rear wheels 12 under the motive power of the vehicle, the shaft 15 being connected by gearing 19 with the shaft '20; This e5 latter mentioned shaftis also journalled in suitable hearings on the auxiliary frame 11, being arranged in spaced parallel relation with the shaft 15', and supporting the drill reel-21. Rising from the rear ends of the n auxiliary frame 11 is a boom 22'which supports adjacent the upper. end thereof spaced superimposed pulleys, 23 and 24t-respective- 1y. The sand line 25,is adapted to be wound about and unwound from the reel 14, and is is trained over the pulley 23 above referred to, while thedrill line 26 is adapted to be wound about and unwound from'the drill reel 21 and is trained over the pulley 24; It will be noted upon inspection. of Figure. 1 that ,the drill line 26 is extended forwardly from the reel 21.and trained over a sliding shaft or' pulley 27 mountedon a transverse rod 28 at the forward end of the auxiliary framer11, which shaft is used to guide the-line 26'for a proper winding about the drum as will be readily understood. This drill line is then trained .over a small pulley 29, arranged adjacent the free end of the drop beam 30. the latter being pivoted upon the rod 28 above referred to and arranged in a.horizontal lane. This beam carries a metallic plate 31 adapted to be engaged bythe arched shaped member 52 which is utilized and operated in a manner to be hereinafter described for as lowering the drop beam 30.

As above stated, the reels are loosely mounted upon their respective shafts, and each reel is adapted to be clutched to the shaft for rotation therewith when its use its is desired. As shown in Figure the reel 14 is provided with a clutch member 32 which is recessed as at 88 to receive the cone shaped projection 34: projecting from one side of the adjacent gear 19, the parts being normally held separated or spaced by a coiled spring 35. rdounted for rotation upon the shaftadjacent one end thereof is a collar 36 having a cam-like projection 37 adapted to be received by a notch 86 formed in the bearing 37 whereby the reel is caused to slide upon the shaft into clutching engagement therewith, when the collar 36 is turned in one direction. Extending from this collar is an arm 38, the upper end of which is connectec with a rod 39 adapted to be operated by a lever to arranged at one end of the machine. This operatesa brake for retarding the rotation of the adjacent drum. The cam shaped projection 37 is normally re ceived by a notch in the adjacentbearing 37 and the parts arranged as shown in Figure 5. The drill reel 21 is also formed with a clutch engaging member 41 which is recessed as at 42 to receive the cone shaped projection 43 forming part of the adjacent gear 19 which parts are normally held eparated by a spring 44. Also mounted for rotation upon the shaft at the other end of the reel is a collar 45 having a cam shaped projection 46, the latter being normally received by a notch formed in a stationary collar 47. Carried by the collar 45 is an arm 48, which arm is connected with a rod 4-9 adapted to be operated by a clutch controlled lever arranged adjacent the lever 40, above referred to. Manifestly, when the collar 45 is rotated on the shaft 20, the cam-like projection 46 cooperates with the stationary collar l? to force the reel 21 longitudinally of the shaft 20 into clutching engagement therewith. Either of the reels can he put into use by selectively operating the levers 40 and 50 above referred to,

Carried by the ends of the shaft 20 are 'c-rank arms 51, and pivoted on these arms :s the arched shaped member utilized to lower the drop beam 30 intermittently during the operation of the drilling mechanism. The arms 51 are provided with projections 53 which are adapted to be received by similarly shaped notches 54 formed on a collar 55-iixed on the shaft 20, so that the arms 51 rotate with the shaft 20. The arched shaped member 52 possesses the desired degree of resiliency, to hold the crank arms 51 engaged with the collars 55 for the purpose just mentioned, the arms however, being mounted for sliding movement on the shaft 20. so that they can be separated from the collars 55 when it is desired to render the crank arms 51 and the adjacent arched shaped member 52 inactive. For this purpose, I make use of a sleeve 56, there being one of these sleeves arranged between each arm 51 and the adjacent side of the auxiliary frame 11, and mounted to slide upon the adjacent collar 55. Each sleeve 56 is controlled by an arm 57 which is mounted to turn upon the shaft 20, between the said sleeve 56 and the adjacent side of the frame 11, the arm being provided with a cam like projection 58 adapted to be normally received within a notch or recess 59 formed in the frame 11 as shown in Figure 5. The arms 57 at the op posite side of the machine are connected by a rod 60 which in turn is operated by a lever 61 arranged at one end of the machine, both of said arms 57 being actuated at one and the same time. Manifestly, when the arms are turned in one direction, the cam shaped projections 58 move out of their re cesses 59, riding against the side of the frame, which of course moves the sleeve 56 outwardly against the crank arms 51 causing the latter to be separated from the collar 55, so that the shaft 20 can rotate without imparting movement to the crank arms 51 for the arched shaped member 52. However, in the normal position of the parts, when'the shaft 20 is rotated, the arched shaped member is moved upon its pivots 62 to be drawn to a position over the drop beam 30,

and when the arched shaped member is low:

cred it en ages the beam 30, lowering the latter to exert a pull upon the drill cable 25 lifting the drill tool an appreciable distance. During the continued rotation of the shaft 20, the arched shaped member 52 is moved upwardly to release the beam 30 allowing the latter to return to its normal po-.

sition by the fall of the drill tool from its elevated position as will be readily understood. This operation is continued as long as the machine is in operation and the arched snaped member 52 located to engage the beam 30. It is possible to shift the arched shaped member 52 to an out of the way position thus rendering it inactive, without disen gaging the crank arms 51 from the collar 55 as above described- For this purpose, the arched shaped member 52 is connected by rod 63 at the opposite sides of the machine, the corresponding extremities of these rods being pivotally connected with vertical lever 6 1 pivoted as at 65 at the opposite sides of the machine. The lower ends of these levers 64: are connected with rod 66 whi h have their other ends connected by a cross rod 6'? which carries a lever 68, so that by operating the latter the arched shaped member 52 can be moved to occupy a position where it cannot be brought into engagement with the drop beam 30. It will be noted upon inspection of Figure 1 that a rod 69 leads from the car buretor of the engine not shown, so that the same can be regulated or controlled by a lever 70 connected with one end of the rod 69. In otherwords all of the controlling le vers above referred to are arranged atone 7 11 and arranged in juxtaposition to the ill arched shaped member 52 is what I'term a bumper 74 which straddles the drop beam 30 and arranged to limit the upward movement of the beam incident to the fall of the drill tool as above described. 7

It might be desired from time to time to gradually feed more line from the reel 21, which may be accomplished by manually operable means including a shaft 75 having a worm gear 76 adapted to mesh with a gear 77 fixed upon the shaft of the drill reel. The shaft 75 is mounted for sliding movement in its bearings 77, and is equipped with a hand wheel 78 through the instrumentality of which the shaft 7 5 is controlled. When it is desired to rotate the reel 21 by hand, the shaft 7 5 is moved toward the car 77 to cause the worm gear 76 to mesh with the latter. The gear 76 automatically releases itself when the drum 21 starts rotating in a counter-clockwise direction, whereupon the shaft 75 with the gear 76 is moved to the right or forwardly in its bearings, the forward bearing-act ng as a stop and with which the gear 7 6 is brought into contact.

The operation of the mechanism is as follows:

The auxiliary frame 11 is of course adapted to be arranged upon an automobile chassis, so that the entire machine can be conveniently moved from place to place, during which the boom 22 lies horizontally upon the frame 11, the boom 22 being pivoted as at 82 to allow it to be swung into this lowered osition. hen it is desired to use the machine the rear wheels 12 arefirst jacked off the ground. The motor is then put into operation, and its speed regulated by the lever 70 connected with the carburetor controlled rod 69. Then either the sand line 25 or the drill line .26 can be used, by selectively operating the reels 14 and 21 respectively by means of the clutches above described. lVhen the drill line 26 is being used, the arched shaped member 52 is reciprocated by the crank arms 51 incident to the rotation of the. shaft 20, and at the same time is afiorded pivotal movement with relation to said arms 51, so as to intermittently engage and lower the drop beam 30, which is subsequently elevated incident to the fall of the drill tool, when the arched shaped member 52 moves away from the beam in its lowermostposition,- The return movement of this beam 1s limited by the bumper 74:.

The invention in its entirety is very. simple in construction, and the parts are so arranged that the attendant occupies a position where he c'a-n watch the-work beingacco'mplished.

\Vhile it is believed that from theforegoing description, the nature and advan tages of the invention will be readily appar ent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.
